Boardwalk Hall, formally known as the Historic Atlantic City Convention Hall, is an arena in Atlantic City, New Jersey, United States. It was Atlantic City's primary convention center until the opening of the Atlantic City Convention Center in 1997. Boardwalk Hall contains the World's largest musical instrument, a pipe organ of over 33,000 pipes, 8 chambers, its console the world's largest of 7 manuals and over 1000 stop keys, and one of two actual 64'stops (the other found in the Sydney Town Hall).
Also included in this organ are pipes which are on 100 inches of pressure, the Grand Ophicleide being the loudest and also most famous. The Guinness Book of World Records states the following "..a pure trumpet note of ear-splitting volume,... six times louder than the loudest train whistle." However, these stops are actually well refined and are not overpowering in Boardwalk hall due to its massive interior size. It was declared a U.S. National Historic Landmark in 1987. The venue seats 10,500 people for ice hockey, and at maximum capacity can accommodate 14,770 for concerts.
